AidChat / Barrier-free Employment


AidChat is a system designed for hearing-imparied waiters in restaurants, mainly consisting of the band and the service bell. Customers call the hearing impaired waiters by the service bell in times of need. Then, waiters receive the call by the bands. The service bell is able to change the voice to the text, and the text will be presented on the band.
AidChat allows hearing impaired restaurant waiters to communicate with customers without obstacles, which improves the work efficiency as well as helps the hearing impaired join the society and get more job opportunities.
